本发明的信息传输装置可以是手机、数码相机、数码摄像机、便携式多媒体播放器、掌上游戏机、平板电脑、笔记本电脑等移动终端。本发明能不需要对移动终端的硬件作任何改动，使得所有移动终端上都能够进行近距离通信，特别是可以使不具有近距离通信模块的最基本的或者比较低端的移动终端也能够进行近距离通信，简单易行且成本低廉。并且，以磁信号为载体进行信息传输，通信距离更加可控，与电磁波和声音相比更不易受干扰，因而在近距离通信中具有很大的优势。
以下结合附图对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
图1为本发明实施例中信息传输方法的流程图。本实施例的信息传输方法，可以实现数据信息从信息传输装置内到信息传输装置外部的单向传输，且传输距离可控，从而使得信息传输装置能够进行设定范围内的近距离通信。
如图1所示，本实施例中，信息传输方法的流程包括：
步骤101，对待传输数据信息进行处理，生成磁场数据或音频文件；磁场数据即磁场格式的数据。
待传输数据信息可以是短信息数据、音频数据、静止图像数据等。
待传输数据信息转换为磁场数据主要包含如下过程：
（a1）磁信号组帧；
（a2）磁信道传输编码；
（a3）磁信号调制。
概括来说，通过磁信号组帧、磁信号传输编码和调制，即生成磁场数据。
磁场数据调制后的波形可以为锯齿波、正弦波、脉冲波等。磁场数据调制的速率为20Hz——20KHz。
磁场数据可以转换为音频数据并以音频文件的格式进行存储。音频文件易于存储，且可以通过各种播放器进行播放，易于在手机等移动终端上的界面操作。
将待传输数据信息转换为音频文件的过程是：
（b1）将上述产生的磁场数据作为音频数据样本，对该音频数据样本进行量化和编码；
（b2）对量化和编码后的数据可以进行压缩等操作；本步骤为非必要步骤；
（b3）在压缩后的信号中加入文件头、文件尾，并按照音频文件的存储格式存储为音频文件，即得到了音频文件。
概括来说，对磁场数据进行量化和编码后再按照音频文件的存储格式进行存储即得到了音频文件。
音频文件可以是声音波形文件、第三代声音文件压缩格式等。
其中，前述的编码方式最基本的为自然二进制编码方式。特别地，在将待传输数据转换为音频文件时，编码方式通常可以为脉冲编码调制、差分脉码调制、自适应差分脉码调制、子带编码等。脉冲编码调制可以为线性脉冲编码调制或对数脉冲编码调制。
在步骤101中，可以将待传输数据信息按照一定的帧格式定义进行组合。可以将待传输数据信息组合为固定长度的帧，也可以组合为非固定长度的帧。对于固定长度的帧，可以先将待传输数据信息划分为多个块，对不同的块采用适合在磁信道中传输的编码方式进行编码。然后由多个块编码后的数据和一些识别帧的标示组成一个固定长度的数据帧。对于非固定长度的帧，可以对固定长度的待传输数据信息进行编码和添加标识码。在组合为帧的过程中，帧的标识码的位置可以固定也可以不固定。对于固定长度的帧来说，标识码可以放置在一帧的开头，也可以位于一帧的中心。对于非固定长度的帧来说，标识码放置在一帧的开头。帧的标识码可以选择为唯一，也可以非唯一，以区分不同类型的帧。
在步骤101中，可以在待传输数据信息中加入一些冗余以提高磁场传输的可靠性，特别地，可以进行检错编码或纠错编码，例如加入循环冗余校验码或卷积码等等。
在步骤101中，可对待传输数据信息进行同步时钟编码，特别地，可以采用曼彻斯特编码或差分曼彻斯特编码。
步骤102，用步骤101中生成的磁场数据或音频文件，生成驱动信号；
如果步骤101中生成的是音频文件，则通过调用播放器播放音频文件，对音频文件进行解码后得到音频样本数据（即磁场数据），再对音频样本数据进行数模转换和功率放大，从而生成驱动信号，用以驱动电声转换装置（例如移动终端中的扬声器）产生磁信号。
如果步骤101中生成的是磁场数据，则对磁场数据进行数模转换和功率放大后，生成驱动信号，直接驱动电声转换装置产生磁信号。
磁场数据与音频文件可以通过相同的硬件通道也可以通过不同的硬件通道进入音频通道，但基本流程都是相同的，即样本数据（音频样本数据或磁场数据）按照一定的速率进入数模转换器转换为模拟信号，再进行功率放大，最后驱动扬声器等电声转换装置。
音频文件通过播放器播放时，先去掉一些文件格式信息，再进行解压缩(不是必须的)等操作，再进行解码后送入数模转换器为模拟信号，再进行功率放大，最后驱动扬声器等电声转换装置。
所以，总体来说，待传输的数据信息可以转换为磁场数据，该数据直接通过硬件通道驱动扬声器；或将磁场数据再转换为音频文件，以播放音频文件的方式驱动扬声器。这两种方式最终都是将要传输的数据通过扬声器发声时的漏磁这个载体传输出去。
步骤103，用步骤102中生成的驱动信号驱动电声转换装置，产生并发送第一磁信号。优选的，电声转换装置中包括线圈，线圈在驱动信号的驱动下，产生包含所述磁场数据或音频文件的第一磁信号，并发出。
在驱动信号的驱动下，一方面，电声转换装置产生包含数据信息的第一磁信号，通过第一磁信号将数据信息发送出去；另一方面，电声转换装置也产生包含数据信息的声音信号，通过声音信号将数据信息发送出去。
可以通过对电声转换装置的功率调整来或通过对传输数据进行不同的调制方式来实现对通信距离的控制，以实现预设近距离范围内的通信。可以通过对电声转换装置的播放速率的调整，来实现对通信速率的控制。
电声转换装置可以是扬声器，例如手机中的喇叭。由于扬声器是信息传输装置，如移动终端的基本部件，所有的移动终端（手机等）都具有扬声器，因此本发明的信息传输方法在任何移动终端上都能实施。并且，不需要对移动终端的硬件作任何改动，只需要在移动终端上加载实施本发明信息传输方法的软件即可。
